A senior official at a Texas tent camp that’s now housing more than 300 migrant children said Monday that even his own staffers don’t believe the Trump administration should have separated migrant families at the border.

“They hate this mission,” the official said of Tornillo staffers, who are not government employees but hired through the private contractor BCFS, which operates the facility. “Everyone who’s working here would go home today.”

On Monday, more than two weeks after the Trump administration opened up Tornillo’s “camp” for migrant children, officials finally opened its doors to reporters.

The shelter, which is about 30 miles east of El Paso, currently holds 326 children, the vast majority of whom entered the United States without authorization and without their parents. Right now, 23 separated children live in Tornillo; three were already reunited with their parents, officials said. Most of the camp’s inhabitants are boys age 13 to 17 from Nicaragua, Guatemala, Honduras, and El Salvador.
